External wastegate on an S5 Tii stock setup

soldave · 09-03-2010, 05:46 AM

How feasible is this? Am running a JDM S5 Tii and it's boost creeping like crazy. Have managed to secure a Trust 50mm wastegate for free and would like to use it is possible to replace my existing wastegate setup. One reason is because the actuator's on its way out I think, not pulling the wastegate door shut on decel, resulting in a rattlesnake sound when driving!

Anyway, have read that it's pretty tough to attach an external wastegate to an S5 exhaust manifold. Can anyone who's tried this comment and let me know if it's possible and not a complete swine to do.

Cheers in advance
